I have a few lights out on my center console. The C/T light was the first to go out. The button still works but is completely dark. Now, the right half of the air placement knob (the one that changes where the air blows from) doesn't illuminate but if I tap on the dash around the knob they come back on.

Check out lmctruck.com they have replacment bulbs with the blue covers i dont know exactly where in the web site they are but the newer chevy trucks have these bulbs also and they sell replacements on the web site.

I have the same problem. I don't have a soldering iron. Even if I did, I still wouldn't be able to do it. I just can't solder.

I wonder if you might be able to somehow use those LED light strips like they sell at Pepboys? I think they're designed to stick on the outside of your car to make it LOOK like you have LED DRLs or something. But if you wired them into the internal wiring somewhere (like the aux wire -yea, they'd be on when the ignition was on, but it seems easier than trying to replace them).
I hope to try it one day. IDK, maybe you'll have better luck soldering.

Going to purchase a few of these bulbs to replace the burned out ones in my Jeep. I have the passenger controls too. They're not all out, but most of them on the left side of it are. I hope it's as easy as you showed to replace them.
